The app is designed to run in the background. App functionality is tightly integrated with its accompanying macOS notification center widget, which is convenient for switching colors, scenes, settings/options and animations for your Bluetooth connected LED lights. The SP110E is "Neopixels" compatible, and is capable of controlling 5V & 12V LED strips/lights. The settings can be further customized from the "Led light Control" app/widget. Due to Bluetooth LE limitations, only one device at a time can connect to the SP110E driver unit.
